Political Assessment of Possible Reactions of EU Main Trading Partners to EU Border Carbon Measures

Henrik Horn and André Sapir

This briefing discusses the possible reactions of the European Union’s larger trading partners to carbon border measures. Section 1 discusses experiences of carbon border adjustment-like regimes prior to the European Commission’s announcement of the Green Deal. It focuses on the EU Aviation Directive, the US policy debate, and the Californian CBA for electricity.

Section 2 considers reactions to the Green Deal announcement, based on informal discussion with officials from major trading partners to the EU. It identifies positive and negative reactions to the principle of an EU CBA, concerns about its design, criticisms and potential policy responses by these partners.

Section 3 discusses the implications of our findings. It points to several features in the design and introduction of an EU CBA mechanism that we believe will importantly affect how partners will react to such mechanism.

COVID-19 and the Consequences for Free Trade

Ewa Björling, Andreas Hatzigeorgiou, Magnus Lodefalk and Fredrik Sjöholm

The response to the COVID-19 pandemic has disrupted global trade, investment and value chains. There is a risk that newly imposed barriers to international trade and mobility will become permanent. Research shows that veiled protectionism in the wake of the COVID-19 pandemic would be associated with greater risks and impede the economic recovery needed to avoid a new economic depression. We argue that failing to reboot free trade and to restore global value chains could aggravate an already difficult and delicate situation in regard to global economic development and poverty reduction. In order to reboot globalization, however, there needs to be a new approach. Simply going over old ground would be insufficient.

The European Union and the Technology Shift

Antonina Bakardjieva Engelbrekt, Anna Michalski and Lars Oxelheim

Without question, technological developments during the 2000s have changed society fundamentally. Much as earlier industrial revolutions redrew economic and political arrangements, the ongoing IT and digital revolutions have far-reaching repercussions for the structure of society.

Thatcher Warned Us to Go Slow on European Integration: Too Bad We Didn’t Listen

Johan Wennström

This November will mark 30 years since former British Prime Minister Margaret Thatcher left office. After she had narrowly failed to secure an outright win in a 1990 leadership contest triggered by a challenge from Michael Heseltine, her former defense secretary, the majority of Thatcher’s Conservative cabinet colleagues withdrew their support and forced her departure following what she described as “eleven-and-a-half wonderful years.”

Seigniorage through periodic recoinage: When the validity of money was restricted in time

Roger Svensson and Andreas Westermark

For almost 200 years, old coins were frequently declared invalid in large part of medieval Europe and had to be exchanged for new ones for an exchange fee. This column shows that frequent recoinage generates incomes for the minting authority when the tax level is low enough and the punishment for using invalid coins is high enough, and when there is a limited coin volume in circulation and also an exchange monopoly. The system is equivalent to the 20th-century idea known as the Gesell tax.

Information Disclosure Rules and Auction Mechanism: How Much Information on Electricity Auctions?

Ewa Lazarczyk and Chloé Le Coq

The information structure is particularly dense in electricity markets. Because electricity storage is currently limited, demand and supply have to match at all times, and up-to-date information about available capacities, as well as forecasted and actual grid conditions, is essential for market participants.
Indeed, both generators and TSOs (along with users and traders) rely on this information to optimize their strategy and make proper risk assessments.

Transition to a Capacity Auction: A Case Study of Ireland

Ewa Lazarczyk and Lisa Ryan

Modern electricity markets are characterized by increasing shares of intermittent production which has almost zero marginal costs. The effect of introducing large amounts of cheap power into the system is known as the merit order effect – a shift of a supply curve to the right which delivers lower equilibrium prices. The lower prices and the fact that fossil-fuel generators are used less often exacerbate adequacy problems – there is a threat that not enough generating capacity will be available in the system since generators´ revenues are low and investment needs are not met. This and the fact that energy markets are often capped in order to prevent market power leads to the so called “missing money problem” (Teirila and Ritz, 2018, Bublitz et al., 2019). One possible remedy is to supplement the energy only markets with capacity markets (Newbery, 2016; Cramton et al, 2013; Joskow, 2007).

CEO Incentives Shown to Yield Positive Societal Benefits

Lars Oxelheim

The negative aspects of large CEO pay and the associated incentives have been a hot political issue in many countries. Our research identifies some positive aspects of CEO incentives in a broader economic/societal context that have been overlooked. In a five-year longitudinal study across major free-market nations in Asia, Europe, and the Americas, we find when a higher proportion of CEOs in a nation receive incentives, that nation’s GDP increases significantly in the following years, independent of the incentives monetary value.​

How Sweden Became More Entrepreneurial Than the US

Fredrik Heyman, Pehr-Johan Norbäck and Lars Persson

Recent studies document a 30-year decline in various measures of dynamism in the US, manifested in a decline in the share of young firms as well as their share of job creation. This column shows that this has not been the case in Sweden. Young firms have been more prominent in the Swedish business sector than in the US in recent decades, and policies to encourage entrepreneurship are key to this.

Dissertation Summary: "On the Move: Essays on the Economic and Political Development of Sweden"

Erik Prawitz

The transformation of Sweden, from an agricultural society in the mid nineteenth century to one of the world’s richest nations at the start of WWI, was remarkable. Beyond the well-documented increase in real wages, Sweden established itself as an entrepreneurial welfare state. In fact, concurrent to the rapid economic upswing, it underwent a period of substantial political change. One of the aims of my dissertation is to shed light on the possible causes behind this striking transformation and, thus, improve on the understanding of why Sweden became Sweden of today—in terms of both its economic and political development.

Credit Ratings and Structured Finance

Jens Josephson and Joel Shapiro

The poor performance of credit ratings of structured finance products in the financial crisis has prompted investigation into the role of credit rating agencies. This column discusses the incidence of rating inflation when such an agency both designs and rates securities, highlighting the role of demand from investors that face rating constraints, such as banks, pension funds, or insurance companies. It finds that ratings are accurate when these constraints are very tight or very lax, but inflated otherwise.

The Exhaustion of Hedgehog Morality

Johan Wennström

This analysis suggests that, as in the 1930s and the Second World War, liberalism today is being confronted by “authoritarianism.” In response, the analysis counsels, liberals should either renew their appeal to voters by persuasively restating their intellectual foundations and historical accomplishments or promote a more muscular version of their creed.

The European Union and the Return of the Nation State

Antonina Bakardjieva Engelbrekt, Anna Michalski and Lars Oxelheim

Ever since the first steps towards European integration were taken in the early 1950s, the relationship between the nation-state and the European Union has been a crucial issue. Throughout the years and in various ways, this relationship has defined the form and scope of European integration.

In particular, the movement towards deeper integration has followed two distinct and partly contrary lines of development: increased supranationalism, in the form of greater powers for the Union; and intensified intergovernmentalism, in the form of closer cooperation amongst the member states, In fact, the EU has embraced both types of integration since its inception.

This can be seen in its treaties, in its common institutions, and in the formulation of its actual policies. However, this essentially natural and balancing relationship has recently been challenged by individual member states acting in their self-interest; and the foundations of European cooperation have been called more and more loudly into question.

This raises two issues: First, if indeed we are witnessing the return of the national-state, in what form is it returning? Second, is the national revival a lasting phenomenon with which the EU must deal for a long time to come, or is it rather a transitory trend?

Early Entry to Verify Quality Stimulates Breakthrough Innovations

Pehr-Johan Norbäck, Lars Persson and Roger Svensson

Most OECD countries provide subsidies to stimulate the entry and growth of small entrepreneurial firms. This column argues that a better policy would be to combine these subsidy schemes with policies that improve the merger and acquisition market for small entrepreneurial firms, because the best strategy for such firms is to make an early entry to market to signal innovation quality and overcome asymmetry problems. Entrepreneurs would be able to create bidding competition among incumbents and receive a higher acquisition price, incentivising them to develop breakthrough innovations that will raise welfare.

‘Post-Truth’ and the Decline of Swedish Education

Magnus Henrekson and Johan Wennström

In the last 15–20 years, Sweden has suffered a downturn in several important aspects of the elementary and secondary education system. To begin to illustrate the state of Sweden’s schools, we can make a comparison with the heavily criticized American education system. It is a common and understandable belief, in the U.S. and elsewhere, that Swedish schools compare favorably with American schools in terms of educational outcomes.

How the Market Can Help Break the Glass Ceiling for Women in Management

Fredrik Heyman, Pehr-Johan Norbäck and Lars Persson

A new CEPR working paper investigates how product market competition and gender-specific management career hurdles affect the gender wage gap for managers. The findings suggest that increased product market competition may not only boost the wages of female managers but also improve overall efficiency.

The European Union in a changing world order

Antonina Bakardjieva Engelbrekt, Anna Michalski and Lars Oxelheim

The world is in a state of upheaval. In the last decade, much of public debate has been dedicated to global power shifts away from the United States and Europe and towards countries with strong economic growth or development potential, such as China, India, Brazil, and South Africa.

The Effects of Digitalisation on Labour Market Polarisation and Tax Revenue

Mårten Blix

Digitalization is sometimes described as the third industrial revolution. What insights can be gained from comparing the present situation to the state of society at the outset of the first industrial revolution some two-and-half centuries ago?

From the late 18th century onwards, it led to an upheaval in work and livelihoods at a time when there were few social safety nets. The rapid transformation of economies and societies triggered a drive to create new social and political institutions to manage and reduce the social costs of change.

Universal education, social security and pension systems were introduced. Spurred by hazardous and difficult work conditions, as well as excessively low pay, labour organised into trade unions to become a counterweight to employers and owners of firms. Societies developed methods to handle change and devised ways to resolve conflict through rules and negotiations, rather than through force.

Fostering Breakthrough Entrepreneurship

Erika Färnstrand Damsgaard, Per Hjertstrand, Pehr-Johan Norbäck, Lars Persson and Helder Vasconcelos

Most developed economies provide significant subsidies to small businesses to encourage innovation. This column argues that while subsidies to reduce entry costs may increase entrepreneurial entry, they can also lead to a reduction in the likelihood of ‘breakthrough’ inventions. Entry costs, which are incurred when an innovation project is successful, prompt small firms and entrepreneurs to pursue high-risk, high-reward innovations.

Structural Change and the Freight Transport Labour Market

Mårten Blix

Nations that have managed to become rich have had institutional features that supported incentives for value creation while ensuring that the ways insiders and special interest groups can extract monopoly rents are limited. Improved skills have been a central component of helping individuals and societies to adapt to technological change.

As technological progress has led to the disappearance of many difficult and arduous jobs, many new jobs have been created with higher skill content, leading to better productivity and real wage growth. In the long run, the modern economy is set to continue to create new jobs, especially in the service sector.

The Duality of the Swedish Labour Market

Lars Calmfors, Petter Danielsson, Ann-Sofie Kolm, Per Skedinger and Toumas Pekkarinen

There are two key developments in the current labour market in Sweden. On the one hand, there is a strong economic upturn fuelled primarily by domestic demand. This means that the non-tradable sectors are doing better than the tradable sectors. There are labour shortages, particularly in the public sector and in the private service sectors. On the other hand, it is difficult for the low skilled, particularly those who are foreign born, to enter the labour market. Both these problems are considered in this report.

The Swedish Health Care System

Anna Häger Glenngård

All three levels of Swedish government are involved in the health care system. At the national level, the Ministry of Health and Social Affairs is responsible for overall health and health care policy, working in concert with eight national government agencies.

At the regional level, 12 county councils and nine regional bodies are responsible for financing and delivering health services to citizens.

At the local level, 290 municipalities are responsible for care of the elderly and the disabled. The local and regional authorities are represented by the Swedish Association of Local Authorities and Regions (SALAR).

Trends and gradients in top tax responses

Enrico Rubolino and Daniel Waldenström

The responsiveness of high-income earners to taxation is a central aspect of tax system design. This column presents patterns in the tax elasticity of top earners for up to 30 countries over a period of 115 years. Tax elasticities vary tremendously over time, space, and income, with a J-shaped pattern emerging over the past century. Tax avoidance behaviour strongly influences the elasticity of the very top earners, while there is less support for the role of labour supply responses across earners.

Political Selection and the Path to Inclusive Meritocracy

Ernesto Dal Bó, Frederico Finan, Olle Folke, Torsten Persson and Johanna Rickne

Ancient Athenians drew lots to determine who served in public office, but oligarchs at that time (and ever since) have argued that there is a trade-off between competence and fair representation. This column uses Swedish population data on cognitive and leadership ability to argue that democracy in Sweden has created government by competent people who are representative of all walks of life. Sweden’s inclusive meritocracy suggests that electoral democracy can help us avoid the tension between representation and competence.

Tax reforms and top incomes

Enrico Rubolino and Daniel Waldenström

The link between tax progressivity and the income distribution is the subject of intense debate. This column presents new evidence from tax reforms during the 1980s and 1990s to examine how reduced progressivity affects top income shares. Reduced progressivity boosted top incomes, particularly for those in the top 0.1% of earners. Income tax changes are therefore a plausible candidate for explaining the recent surge in income inequality.

Policy Brief on Institutional Reform for Enhanced Innovation and Entrepreneurship in Europe

Niklas Elert, Magnus Henrekson and Mikael Stenkula

We argue that institutional changes in a liberalizing direction are a sine qua non for economies of the European Union to become more entrepreneurial in order to promote innovation and economic growth.

However, this does not mean that one-size-fits-all policy reforms towards freer markets are likely to be successful. An important reason is that the 28 union member states have very different histories, and distinct institutional structures, affecting their efficiency and the viability of reforming them.

Policy Brief on The Institutional Evolution of Labour Market Institutions in Europe and Entrepreneurship

Gerarda Westerhuis and Magnus Henrekson

What is the impact of labour market institutions on entrepreneurial activity? Recently it has been argued that flexible labour market institutions have a positive influence on entrepreneurial activity. No doubt, labour mobility is an important condition for entrepreneurship.

The institutions governing the allocation of labour and talent in society enable entrepreneurs to develop their businesses and affect the willingness of employees to be(come) entrepreneurial. We analyse these institutions by reviewing labour market regulation in European countries from a historical perspective. We focus on three pillars: regulation of labour markets, wage-setting institutions and social insurance systems.

The European Union and the Return of the Nation State

9783030350048_200x_the-european-union-and-the-return-of-the-nation-state.jpg

This book explores the complex and ever-changing relationship between the European Union and its member states. The recent surge in tension in this relationship has been prompted by the actions of some member state governments as they question fundamental EU values and principles and refuse to implement common decisions seemingly on the basis of narrowly defined national interests.
